Distribution extension of Dasyonchocotyle dasyatis (Yamaguti, 1968) Boeger & Kritsky, 1989 (Monogenea: Hexabothriidae) in Dasyatis longa (Garman, 1880) (Myliobatiformes: Dasyatidae) from Sinaloa, México

Abstract

The collection of 13 specimens of Dasyonchocotyle dasyatis (Yamaguti, 1968) Boeger & Kritsky, 1989 on the coast of Sinaloa, México extends the geographic distribution of the species from the original locality (Hawaii, U.S.A.) eastward to at least the Pacific Coast of Mexico. The species is a parasite of Dasyatis longa (Garman, 1880), a common stingray of the tropical eastern Pacific. This species has not been reported since the original description in 1968.
